Soybean induced resistance to Spodoptera eridania herbivory

open access: yesPest Management Science, EarlyView.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Cannibalism in Buchananiella whitei (Hemiptera: Anthocoridae) and its intraguild interactions with seven predatory mites (Acari: Phytoseiidae & Laelapidae)

open access: yesPest Management Science, EarlyView.
Extraguild prey reduces cannibalism and intraguild predation in Buchananiella whitei, while first‐instar nymphs dominate most predatory mites, with outcomes affected by body size and behavioral traits. Abstract BACKGROUND Cannibalism and intraguild predation (IGP) are common interactions among predators that can influence the effectiveness of ...
